A collection of SCMI core and transport fixes addressing resource lifetimes, teardown races and error handling. Most of these issues are reported by Sashiko as existing issues while reviewing new feature additions to SCMI. The changes: - publish channel state before mailbox and SMC callbacks can run, - quiesce notification work before tearing down transport channels, - fix partial channel setup and mailbox allocation cleanup, - make IDR iteration and shared-channel teardown safe, - correct SCMI device, OF node, handle, bus ID and SystemPower lifetimes;, - harden requested-device registration and removal against races and partial failures, - reject out-of-range DT protocol IDs, and - simplify notification allocations using flexible arrays. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmpjMg8ACgkQAEG6vDF+ 4pg3Kw/+N09f4Zd1c8xwQi5NEfwv8uEKRE73VSAL18aNn89mGj6J1cGOs1NWHJ0b bKDOuhoJWYynHDGbaZGFVLhh3l2Jj2yE+Hr9sq2nOHktA7HFqSVV5ea8RuRD/XHt 3rNIX6UBLSEp7N40ehkwD506zr3eRcfwtUwS8taEvl0NWNKrPJ+TpMxN3LBGWzBq oXaD7642Mb9rDyApuwOGWlHitDPU1qQv5JrLLWP8/Nx4PQlb1TX6171FXvrMdjdx qKUiUBZM9Q9w4gaKgnIEcq0KCBWdxa5ZKPupZTUzt60NEpkemjYcmjxoJFDIArGC 013Z/dXhynkigaEjfvWPhoNaoLx1Q3NTk5ChljaKLizI6sE0N02wuax8rHIuKSnL fhbyNcpmsEgiVwnX4zw6l44AakWHx8qkE3avtx0yks+joAWt8ERzIHCd+uWF1z15 b18humBSxcs3DmmejH8JMMCTpL7OxI3PHtdntttXWpvM43/pZnO6vF23Nfo0KQ3q ZrOD15W4qQ8M9nGKmpaa6f6tDPoWuULLcMhMHZo3FLdOYa5lnGtAs1Rj7MvJ5I0b u8/t4P2hoCskSVN973P51ZA3r1NI9ZK+uZ3Krq9TFEvgI5ZZQTfDoz6Zc4q9/ERV 80k8/wRP8vCjBM2mQ+WVlWG1gJEq487t6bBPfQVeHmS+/BI0g+s= =w04g -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmpjjIsACgkQmmx57+YA GNmWgQ//e5oKyKC8Ac6vcjbRbwb6joIX0u0N8slFoKi3rano2Hb0e0TOLSywjCq8 w2G/n5tBjZKfp9RSqSWY0lZHjZhyyokosiSldtr8rX6v0LLQurHIPHakFHI0uW1h 1iquU37P+TJ8C/EcBHcG/3jrvMGPO2PFln7+XVNE2eG2Q79E26NcU9sNoLJeBTlt AZrwpJ9jnUnay+zbc5jtqxqN50cam5I+lNNu+sZmDd67rN+wOUX68yn8vE6Buk+5 li1Ni0W6sKTbMchx+G56ibqnvTcLnouD5wvSNcgJOVycYsykzMB6pSKgqnUGqBTu uHtvRJ1/Nzp+iQqdiGnzGw4x4bB7tackKIQtOww2wUYuE9KY+OCmnieS3hPpg/Od kRBHrxaZ6fyfb++Mw+Ze5gwFEwhQDI0UgGAqu7DsSAuWefcCdPTo4ia9G+HGS1ID 80SNS/GdUmtLdCfsVIqOtvOY2TKwgfsqBWgimyF2apl3nQgbAUkjUlLTUTIFbhXo em2oi6yLQVvte3HGc5r9NbmBnO3KRYIXYRU+t73bOBYeAKNdIPsA357dcrx/5MnN eGli+DrKk/oC1zrvl9OjpAcD83enZ76EPHKRav8zGAnYQ1sLS+GweJsbSg9Yj4Dq XbJGb8LM7mCFefrDvZKOVSWy5DMazHiofguPBOSgEnqASdp+Ydo= =JO1v -----END PGP SIGNATURE----- Merge tag 'scmi-updates-7.3' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates/fixes for v7.3 A collection of SCMI core and transport fixes addressing resource lifetimes, teardown races and error handling.
